Patented Dec. 31, 1935 PATENT OFFICE NQSE PAD SUPPORT FOR EYEGLASS AND SPEOTACLE FRAMES Charles J. Eagle, Rochester, N. Y., assignor to Artraft Optical Co. 1110., Rochester, N. Y.

Application September 15, 1934, Serial No. 744,112 3 Claims. (01. 88-49) This invention relates to supports for rocking nose pads for eyeglass and spectacle frames and has for one of its objects to provide a novel form of locking means for locking the nose pad to the guard arm.

Another object of this invention is to provide the nose pad with a novel form of support which permits the nose pad to be held rigid for the adjustment of the guard arm.

A further object of this invention is to so construct the rocking pad support that the pad can be quickly and easily attached to and removed from the guard arm.

Another object of this invention is to so construct the rocking pad support that the pad can be easily and quickly removed from the guard arm with the aid of simple tools.

Another object of this invention is to so con-' ence being had to the accompanying drawing in which Figure 1 is an enlarged detailed perspective view of the rocking nose pad and its support on the guard arm.

Figure 2 is an enlarged rear elevation of one of the nose pads. A

Figure 3 is a vertical sectional View of the nose pad, the section being taken on the line 3:13-31: of Figure 2.

Figure 4 is a detail side elevation of the end of the guard arm provided with the rocking pad mounting.

Figure 5 is a top plan view thereof.

Figure 6 is a vertical sectional view of the nose pad, the section being taken on the line (ix-45a: of Figure 1.

. Figure '7 is a side elevation of a modified form of the mounting formed on the end of the guard arm.

Figure 8 is a top plan view of this modified form of the mounting.

Figure 9 is a detail perspective view of a modified form of the metal core of the nose pad and the bearing member thereof.

Figure 10 is a detail perspective view of another modified form of the metal core for the nose pad and the bearing member thereof.

In the several figures of the drawing like reference numerals indicate like parts.

The rocking pad support forming the subject matter of my present invention is formed on the end of the guard arm I and comprises an extension 2 thereof of reduced and substantially rectangular cross section. In forming this exten- 1o sion on the guard arm a transverse shoulder 3 is provided on the outside of the guard arm at the beginning of the extension. This shoulder may be supplemented by a shoulder 4 at the top of the guard arm and a shoulder 5 at the bottom 15 thereof. The inside of the extension 2 is left flush with the inside of the guard arm and forms continuation thereof.

The outer end of the extension 3 forming the rocking pad support is split by the horizontal slit 20 6 which extends rearwardly thereof and divides the outerend of the extension 3 into two prongs i and 8 which are adapted to be bent for a purpose that will presentlyappear.

The nose pad 9, which is carried by the support of the guard arm, is provided with the hear-- ing sleeve or tubular journal bearing H) which has a substantially rectangular cross section with a. rectangular bore having inside dimensions which are slightly greater than the outside di- 30.

mension of the corresponding cross section of the support formed by the extension 2 of the guard arm. This bearing sleeve may be formed of suitable tubing or be bent from fiat stock with the open side fastened to the side of the nose pad. In pads in which the outside is covered with celluloid or similar material the bearing sleeve is suitably attached to the metal core H thereof and projects thru the covering so that the inside wall of the attached portion of the bearing sleeve is substantially flush with the outside of the covering of the nose pad. In this way the inside wall of the bearing sleeve keeps the mounting from binding against the pad as will hereinafter be described.

In attaching the nose pad to the guard arm, the bearing sleeve is slipped over the extension thereof against the shoulders 3, 4, and 5 as 11- lustrated in dotted lines in Figure 4. In this position the slit 6 extends from the end of the guard arm to within a short distance of the inside of the bearing sleeve. An optical screw driver is then inserted into the slit and the prongs l and 8 are separated by bending them up and down respectively on the outside of the bearing sleeve as illustrated in dotted lines in Figure 4 and in full lines in Figure 1. The end of the prongs then form shoulders which prevent an endwise movement of the bearing sleeve on the guard arm and thus lock the nose pad to the guard arm.

While the nose pad is locked to the guard arm the reduced cross section thereof permits a limited rocking movement of the bearing sleeve on the guard arm and this movement is limited by the metal to metal contact of the corners of the extension with the inner wall of the bearing sleeve which keeps the movement fixed and prevents the nose pad covering from being worn away by contact with the guard arm.

In removing the nose pad from the guard arm, a pair of optical pliers are used to simply bend the prongs l and 8 together substantially parallel to each other so as to permit the bearing sleeve H! to again slide over them.

The outside of the bearing sleeve is made flat and substantially parallel to the Wall of the nose pad in order that a pair of pliers can engage the flat outside of the bearing sleeve with one jaw and the outside of the nose pad'with the other jaw so as to hold the nose pad with the bearing sleeve absolutely fixed while the guard arm can be bent to hold the nose pad in the proper angular position thereon.

In Figures '7 and 8 I have illustrated a modified form of the support provided on the end of the guard arm. In this modification suitable shoulders l4 and I5 are provided at the top and bottom of the guard arm a suitable distance from the end of the guard arm and the guard arm is slit vertically to provide a bendable prong l6 which can be bent outwardly to hold the bearing sleeve ID in place on the guard arm as illustrated in dotted line in Figure 8.

In the modified form of the metal core for the nose pad illustrated in Figure 9, the bearing member is provided by a pair of lugs I! and I8 which are perforated with a substantially rectangular opening and are struck up from the sides of the metal core parallel to each other.

In the form of the metal core for the nose pad illustrated in Figure 10 the bearing member 20 is struck out from the core in the form of a sleeve.

I claim:

1. In a nose pad support the combination of a nose pad, a substantially horizontal tubular journal bearing having a rectangular bore provided 10 at the back of said nose pad, a substantially horizontal supporting arm having a rectangular cross section corresponding to but smaller than the bore of said tubular journal bearing engaging into said bearing to support said nose pad and. permit a lateral nonbinding rocking movement of said pad on said supporting arm limited by the contact or the corners of said supporting arm with the sides of the bore of said bearing.

2. In a nose pad support the combination of a nose pad having a nonmetallic cover at the back thereof, a substantially horizontal tubular journal bearing having a rectangular bore projecting from the back thereof with one side of the journal bearing spacing its bore from the pad, a substantially horizontal supporting arm having a rectangular cross section corresponding to but smaller than the bore of said bearing projectjecting thru said bearing to provide a nonbinding lateral rocking movement of said pad on said supporting arm limited by the contact of the corners of said supporting arm with the sides of said bearing to keep said corners of said supporting arm from Wearing into said non-metallie cover of said pad.

3. In a nose pad support the combination as set forth in claim 1 in which the free end of said horizontal supporting arm is split to permit its expansion on the outside of said journal bearing.
